Frequently Asked Questions

What is a Monoblock LNB?

This design consists of two independent LNBs in a single housing and allows a user the potential of receiving the signal from two different satellites which are at slightly different orbital positions from a single dish installation. The switching between the satellites is achieved via the use of DiSEqC signals. Monoblock LNB's are available mostly for satellites with a fixed 2°/3°/4.3° or 6° spacing and the range covers Ku band Monoblock switch single, twin and quad outputs. For example where a 2° Monoblock LNB could be used is for the reception of 5°W and 7° W or with 3° distance for the reception of 13° E and 16° E.

Why It Exists: The Problem It Solves

Many TV channels and services are broadcast from clusters of satellites positioned close together in the sky (e.g., 6°, 4.3°, or 3° apart). Instead of installing two separate dishes or a heavy, expensive motorized dish to swing between them, a Monoblock LNBF provides a simple, fixed, and cost-effective solution.

How It Works

Two LNBs in One Housing: The "block" in Monoblock refers to the single, integrated unit. The two LNBs are not adjustable; their spacing is factory-set for a specific satellite orbital separation.
Fixed Angle (Skew): The unit is designed to be mounted centrally on the dish's arm. The skew (rotation) of the entire block is adjusted during installation to match the polarization angle for both satellites.
Dish Size Requirement: Because the dish's focal point is optimally aligned for the primary satellite, the secondary satellite is slightly "off-focus." Therefore, a larger-than-minimum dish size (often 80cm or larger in Europe) is usually recommended.
Connection: A Monoblock LNBF has two output cables (one for each satellite). These connect directly to a satellite receiver with two independent tuners or to a multi-switch to feed multiple receivers.

Common Uses

European Free-to-Air (FTA): The classic combo is Astra 19.2°E (German, French, international channels) and Hotbird 13.0°E (Italian, Middle Eastern, Eastern European channels). A 6° Monoblock is standard for this.
International Content: Popular in expatriate communities to receive channels from two nearby satellites from their home country.
Simultaneous Recording/Watching: Allows one tuner to record from a channel on Satellite A while watching a channel on Satellite B.

How to Choose the Right LNB

"How many satellites do I need?"

One satellite → Single/Twin/Quad LNB
Two nearby satellites → Monoblock (or motorized dish)

"How many receivers/TVs do I need to feed?"

One TV → Single LNB
Two TVs from one satellite → Twin LNB
3-4 TVs from one satellite → Quad LNB
Two TVs from two satellites → Monoblock Twin
